Westlake University Team Develops Ice-Assisted van der Waals Metal Contact Technology, Breaking Through Perovskite Device Interface Challenges
Recently, the research group led by Professor Min Qiu from School of Engineering, Westlake University developed a novel ice-assisted van der Waals metal contact technology, addressing a major challenge in perosvkite-electrode interface of halide perovskite devices. Due to the "soft lattice" nature of perovskites, traditional electrode fabrication processes easily introduce defects at the peros...
MORELight-Controlled Mechanical Oscillator Utilizing the Van der Waals Force
At the microscale, surface forces between objects far exceed volume forces like gravity, making contact adhesion highly likely: two closely positioned objects become difficult to separate due to surface forces. For dry, uncharged surfaces, the van der Waals force is typically the dominant surface force. Because the Van der Waals force hinders and restricts movement, researchers designing mechan...
MORE3.8g, mass producible SiC diffractive waveguide without Rainbow Artifacts
Since its inception, augmented reality (AR) technology has faced a persistent engineering challenge: achieving a wide field of view (FOV) and excellent display quality within a compact and lightweight form factor. Diffractive waveguide technology is recognized as the mainstream solution for AR displays due to its optimal balance of a thin profile, wide FOV, and mass production potential. Howeve...

MOREBreakthrough in Micro/Nanofabrication on Living Organisms: Scientists Successfully "Tattoo" Tardigrades
Recently, a research team led by Professor Min Qiu from Westlake University achieved a significant breakthrough at the intersection of micro/nanofabrication and bioscience. They successfully created precise micro/nanoscale patterns on the surface of tardigrades—often hailed as the "hardiest creatures on Earth"—and utilized these functional patterns to effectively control their movement. This ...
